I had a system ipython notebook installed on my Ubuntu 14.04 via apt-get. To upgrade the notebook to the newest version, I ran
sudo pip install ipython[notebook] -U
This installed version 3.0.0 of ipython. But when I run ipython, the old version still starts. What is the correct way of using the pip's version?
python
, which version of Python does the interpreter say you are using? – dukebody May 21 '15 at 14:31
